Please support Display(Order = ...) with autogenerated Grid columns.

Such functionality will also be useful for controlling the order of manually declared columns when using a custom component for reusable columns. For example: https://blazorrepl.telerik.com/cGOtbwOX21f6zQcy35 - the "Name" column is rendered last and currently one cannot control its order.

public class DateModel
{
  [Display(Order = 2)]
  public string Id { get; set; }
  [Display(Order = 1)]
  public string Text { get; set; }
}

I would prefer if you can use the FilterMenuTemplate in such a way that you can fetch also "filter criteria" from other fields/columns.

An example:

- grid has 3 coluns > Name, City, Population

- filter mode is set to filter menu and my filter menu should display at the first column.

- after the filter dialog is opened my expactation is that it includes also entries from other fields

In summary, my team would welcome the opportunity of central approach for filtering with multiple fields.

Regards,

Özmen

AutoFitting all columns should not leave blank space in the Grid, the last column should take the available space.

This functionality might be triggered by a setting a bool parameter to true. 

I would like to set increase the searchbox width with a parameter.

ADMIN EDIT

Here is a CSS workaround:

<style>
    .custom-searchbox-width .k-grid-search {
        width: 50%;
    }
</style>

<TelerikGrid Data=@GridData Pageable="true" Height="400px" Class="custom-searchbox-width">
    <GridToolBar>
        <span class="k-toolbar-spacer"></span> @* add this spacer to keep the searchbox on the right *@
        <GridSearchBox />
    </GridToolBar>
    <GridColumns>
        <GridColumn Field="@(nameof(Employee.EmployeeId))" />
        <GridColumn Field=@nameof(Employee.Name) />
        <GridColumn Field=@nameof(Employee.Team) Title="Team" />
        <GridColumn Field=@nameof(Employee.IsOnLeave) Title="On Vacation" />
    </GridColumns>
</TelerikGrid>

@code {
    public List<Employee> GridData { get; set; }

    protected override void OnInitialized()
    {
        GridData = new List<Employee>();
        var rand = new Random();
        for (int i = 0; i < 15; i++)
        {
            GridData.Add(new Employee()
            {
                EmployeeId = i,
                Name = "Employee " + i.ToString(),
                Team = "Team " + i % 3,
                IsOnLeave = i % 2 == 0
            });
        }
    }

    public class Employee
    {
        public int EmployeeId { get; set; }
        public string Name { get; set; }
        public string Team { get; set; }
        public bool IsOnLeave { get; set; }
    }
}

I'd like to be able to enable the Column Chooser menu on just the Command Column and then keep all the other column menus as-is (I have a combination of various custom filter controls on them, so I don't watch to switch to the Column Menu)

When storing and restoring grid state, the selected page size is not included as part of that state currently, and needs to be stored seperately.

(When using GridPagerSettings, the user can select the page size based on inputs provided to PageSizes param. This selection is not synced and will revert to default each time the grid is loaded.

Hi, please expose a property in TelerikGrid where we can set the number of virtual columns to load in advance. A lot of times we would like to load data in advance for 5-10 columns left & right of the current viewport, so the user doesn't see empty columns while scrolling. This may apply to rows as well. It would be very helpful to have this property, please consider exposing it. Thank you.

============

The column Virtualization feature improves the Grid performance when it has a lot of columns. This does not include loading data on demand, but rather UI virtualization. All the data is retrieved and the performance optimization is achieved by rendering only the columns for the current Grid viewport. When the user scrolls horizontally the content for the other columns is rendered and while this happens, the cells appear empty. The requested parameter will control the number of columns that will be rendered in the current viewport but will not be visible until the user scrolls. Thus, the user will not see empty columns.

Hi, please expose the debounce delay as a property of TelerikGrid so we can set how soon virtualized columns are loaded after the user scrolls.

**Admin Edit**

This feature request requires research, and if such DebounceDelay parameter can work with good quality in all cases - it will be implemented. Additionally, we will revise the feature together with loading next set of columns if it will be applicable.

I suggest adding a FieldExpression property to the GridColumn so a developer would not need to create view models and templates for simple transformations of the existing model's properties. The field expression would be used for filtering and sorting as well. Its type would be Func<T, object> or Expression<Func<T, object>>.

   <TelerikGrid Data="@Persons">
            <GridColumns>
                <GridColumn FieldExpression="@(p => p.FirstName + " " + p.LastName)" />
            </GridColumns>
        </TelerikGrid>

Right now you can create a template in the grid to display text from a list based on the foreign key in the grid data. For example, if your database has a table user list and a table role. The Role table has an integer Id primary key column and a text Description column. The user table has a foreign key integer column that is the Role Id. You can bring all the data over when you call up the data (flattening the data) or you can just bring over the foreign key integer value for the role and then create templates.

The situation is described here:

https://docs.telerik.com/blazor-ui/knowledge-base/grids-foreign-key

When you do not flatten the data, you would need to retrieve the role collection and then reference that data in templates in the grid. You need a template for the grid itself, a template for filtering, and a template for the grouping. Maybe more that I am not finding?

What would be great is if you could simply set the foreign key collection for the column and not have to create any templates. You would have to also set what the Id and display text fields are on the collection also so the grid would know what data to use for finding and displaying the desired data. You could require a standard collection with standard field names and then we would have to project the values into it from our other collections using linq.

If a developer changes the structure of the grid in a new release, such as adding or removing columns, the restore can have very unexpected results.

We get around this by storing a version number with the grid and incrementing that number when we change the grid columns.  If the version number on the grid does not match the version number stored with the state, we don't restore it.

We would like to see this be more of an automatic feature of the grid.

Compare the columns in the saved state with the columns in the Grid declaration. You may need to change the way the Grid columns are declared, according to the the linked documentation. If there is inconsistency between the two collections, strip the column information from the saved state before restoring it.  (This was suggested by Dimo from Telerik in a support ticket)

An alternative would just be to throw away that state when it can't be safely restored.

It is impractical to set the grid columns to fixed width. I'll explain with example:

I have grid with 4 columns. The grid should have width 100%.

- Column 1: short text, 10-15 characters. I need this one to auto width to content.

- Column 2: checkbox, also auto-width to header title.

- Column 3: free text that may wrap on multiple lines. I need this column to use all available horizontal space so it will push the 4th column to the very right.

- Column 4: button. auto-width to either header title or button width, whichever is wider.

The auto-width feature is already requested: Autofit column widths on data load (telerik.com) but I don't see a feature request to handle the Column 3 scenario.

Our application has, on many pages, complex business logic to enable or disable specific cells based upon the viewing mode, the user's capabilities, the type of data in the row, etc.   If a cell is to be disabled, we also want to change the background color..  This is easily accomplished with the OnCellRender property.

However, we cannot enable/disable specific cells within a column without creating a column template with conditional logic.  And so, in all our grids, EVERY column has to have a template, just for that trivial function.  And now we have business logic smeared across both the razor page and the code page. 

A template should be required only if you are doing something unusual or exceptional.  Setting a cell to be enabled or disabled is completely routine, and one should not have to create a template just for that.

If you would add a property such as OnCellEnable, to override the column Enabled property on a per-cell basis, it would be extremely useful and would eliminate the need for literally hundreds of templates.

Thanks

Using OnRowDrop works fine but there is no configuration possible to set the column at the end of the grid.

Of course it's a personnal taste but I like to have the all the actions buttons on the right side

In Grid with Filter Menu, I want to trigger the Filter button on Enter press while the focus is still on the filter input.

Currently, it is possible to fire filtering from keyboard only if you tab through the Filter Menu elements to focus the Filter button and then press Enter.
